Why not just use the standard try/catch? It has a built-in instnaceof and it is much easier on the eyes.
try {
//something that may throw exceptions here
} catch (InvalidCredentialsException ice) {
// do something to display message.
} catch (SomeOtherException soe)
// do something ELSE to display message.
} catch (Exception e) {
//generic exception
}
